A NURSING home director has testified she told accused murderer Megan Jean Haines three nursing home residents had made complaints against her before two of them died.

St Andrew's aged care centre director of care Wendy Turner told Sydney Supreme Court she had handed Ms Haines documents the previous night outlining two complaints against her, and had told her the names of the residents who had filed them.

The court heard four phone call recordings made the morning Marie Darragh and Isabella Spencer died in their beds in May 2014.

Ms Haines was calling Ms Turner to arrange a meeting to discuss the complaints.

"Is it normal to have so many complaints or is it just me?" Haines asked on one recording.
